#We use the following function to try to find the quickest pitstop time that isnlt a drive thru penalty

#Use the heuristic that the drive thru penalty is at least 2.5s faster than the fastest pitstop

#and that the 10 quickest pitstops are unlikely to have a range greater than 2.5 seconds.

#This further assumes there are no more than 9 drive thru penalties in a given race

#BUG? the else returned value should be x not the originally posted x[-1] used to generate the images in the orginal f1datajunkie blog post? But a quick check on that shows odd things happening? Too late/too tired to try to debug it tonight...:-( BAH:-()
